keys to change the order of
the nodes listed on the WHO screen. Put the
processor at the top of the list and try to
re–ATTACH.
Not a Processor
Or you are trying to ATTACH
the HHT to a non–existent
device, or no devices are
shown on the WHO screen.
Changing the communication parameters of the
HHT in the node configuration menu. From the
WHO screen, press
[F4] – NODE_CFG.
Try
changing the baud rate by pressing
[F3] BAUD
,
the node address by pressing
[F1] CHG_ADR
,
or the maximum node address by pressing
[F2]
MAX_ADR
. Try different combinations. (The
processor defaults at node address 1 and baud
rate 19200.)
Program Files
Differ
The ladder program in the
processor memory does not
match the program stored in
the HHT memory.
Making the programs the same by either uploading
the processor program into the HHT (overwriting
the HHT memory) or downloading the HHT
program to the processor (overwriting the
processor memory). Caution: The overwritten
program is lost.
Warning:
Undefined I/O
Referenced The address you entered
does not match the I/O
configuration.
Either changing the address to agree with the
configured I/O modules or exiting the edit mode
and re–configuring the I/O to match the entered
address. For the latter, refer to chapter 3, Creating
a Program, for extra help.
